1. 65 TF2 keys
2. 2015-11-30 19:52 - "HoMM's Key Shop - Add for more trades :)"
Keys bought with BTC. The transaction is "completed", but I did not receive any keys.
I received a message like "My inventory is full...", after made some room for my inventory, there is no offer sent anymore.

Update: Solved

I found this in your bot's Steam inventory history:

I think you have already withdrew/spent the keys at some point.
